graphite).
(i) Given that the enthalpy and entropy of formation of methane are –74.85
kJ mol –1 and –80.67 J K–1 mol –1 respectively at 298 K, calculate the
standard Gibbs energy for the dissociation and the equilibrium constant
K. [5]
(ii) Deduce the expression for the degree of dissociation α (also known as
extent of reaction) for this reaction.
